To all whom it may concern:

Be it known that I, DONALD DONALD, a citizen of New-Zealand, residing atMasterton. New Zealand, have invented certain new and usefulImprovements in Baling-Presses, of which the following is aspecification.

This invention relates to improvements in baling-prcsses. and moreparticularly in manually-operated presses which can be made incomparatively light and portable form and are especially adapted for useon farms and at stations where the heavy powerdriven presses cannot behad.

The invention consists in the matters hereinafter set forth and moreparticularly pointed out in the appended claims when considered inconnection with the accompanying drawings, in which Figure 1 is a sideelevation of the press as it appears when loaded ready for thecompressing operation to begin. Fig. 2 is a sectional side elevationthereof. Fig. 3 is an end elevation thereof. Fig. 4 is a side elevationof the press as it appears when the upper box is swung down upon theground. Fig. 5 is a top plan view of the press as it appears when theupper box is swung down upon the ground and the door of the lower box isopened to admit the carriage, which is here shown as occupying aposition part way within the lower box. Fig. 6 is an enlarged sideelevation of the jack mechanism. Fig. 7 is a sectional detailthereof,'taken on line 7 7 of Fig. 6. Fig. 8 is a perspective detail ofthe device for fastening the edges of the cloth within which the bale isformed. Fig. 9 is a sectional detail showing the manner in which the topplate is secured within the end of the upper box. Fig. 10 is a sectionalside elevation of a carriage and bale as they appear when withdrawn fromthe lower box after the com pressing operation is complete. Fig. 11 is aperspective view of a modified form of press embodying my constructionin parts. Fig. 12 is a side elevation of the press as it appears whilebeing used without the boxes.

The press thus illustrated consists of two by pivotally-connected ironstraps 1 and 2, so

that the top box can be swung down until it rests upon the groundopposite the lower box, as shown in Fig. 4. Said lower box is simply afour-sided inclosure open at both ends and bound around bystiffening-bands 3, preferably of angle-iron, which prevent its sidesfrom bulging under pressure. The upper box A is of similar but somewhatlighter construction, which in its raised position fits closely upon theupper end of the box B and forms, in efifect, a continuation orextension thereof. One side 4 of the lower box A is made in the form ofa door, which can be swung open to admit a carriage (l, which consistsof a rectangular base-plate 5 and vertical standards 6, secured toopposite sides of its base-plate and carrying jack devices D at theirupper ends. The baseplate 5 is rectangular in shape and just largeenough to fit within the lower box when closed, except that it hasprojections 7 at the middle of two of its opposite sides, which extendout through recesses or notches 8 in the corresponding sides of the box.rolled into the box are accommodated by slots '9 in the sides of the boxB and by openings 10, left between the Wide ends of taperedfilling-blocks I), that are provided on these sides of the box withinthe angle-iron bands 3, which latter to form a sort of girderconstruction.

Cooperating with each of the jack devices D and forming a part thereofis a verticallymovable rack-bar 11, having upwardly-pointing teeth onits inner face, which are adapted to be engaged in alternation byloop-shaped links or pawls 12 and 13 of the jack, the ratchet-bar beingdrawn down through these loops as the jack is operated. This operationof the jack is accomplished in the usual manner by a lever 14, which canbeswung up and down to give movement to an oscillating fulcrum 15. Thelinks 12 and 13 are pivotally connected with this fulcrum on oppositesides of its center, as caused to alternately slide up over and pulldown upon the teeth of the rack-bar, against which they are held bysprings s. The pivotal point of the outer pawl 13 is preferably arrangedfarther from the center than that of are here bent around them so asThese standards when the carriage is shown, and are thus the inner pawl12, so that during the downward movement of the lever, when the weightof the body can be thrown upon it, the leverage is reduced and theeffective movement increased, as compared with that which occurs whenthe lever is lifted, as it must necessarily be, by main strength.

The ratchet-bars 11 are of such length that they may be raised to fullheight of the top box A when the latter is superposed upon the lower boxand are adapted to be detachably connected with a cap or top plate 16,which fits within the box A and forms the opposing surface of the pressto the base-plate 5. As herein shown, a transverse bar 17 of this capprojects out through the sides of the box and is temporarily secured tothe upper ends of the ratchet-bars 11 by loops 18, and to accommodatethis bar and permit the cap to be drawn down the full depth of the box Aits sides are also provided with vertical slots 9 and its angle-ironswith filling-blocks 72, separated by openings 10, like the correspondingparts of the lower box B.

In the operation of the press the top box A is swung over upon itshinges until it rests upon the ground opposite the lower box B, Figs.and 5. The cap-plate 16 is then slid into the (now) lower end of the boxA and allowed to rest upon cleats 19 on the inner sides of the box,which is cut out at one end of these cleats to admit of the insertion ofthe cap-plate in this manner, Fig-11. The carriage C, having then beenpushed into the lower box A, the open side or door 4; of the latter isclosed and fastened by swing-linksL or the like, and the box is thenlined with a cloth or envelop E, within which the bale is to beinclosed, the cap-plate 16 being covered with a rectangular piece 6 ofsimilar material for closing the head of the bale. Both boxes are thenfilled to the limit of their capacity with the material to be baled, andthe top box A is swung back upon thebox B, as shown in Figs. 1 and 2 ofthe drawings. The cap-plate now occupies the extreme top of the upperbox, and all the material to be compressed is contained within thecontinuous receptacle formed by the two boxes between the base-plate 5of the press and this cap-plate 16. The ratchet-bars 11 can now belifted and connected to the cap-plate by their links 18, and thereuponthe operation of the jack devices moving their levers 14 likepumphandles will force all the material in the upper box down into thelower one. The compressing" operation is now complete,.and it onlyremains to sew the top piece E to the rest of the bale-cover and removethe bale from the press. To accomplish this, the top box is swung backupon the ground, the side or door 4, of the lower box is opened, and thepress-carriage C withdrawn bodily, Fig. 10, together with the bale,which is still held tightly compressed between the base and top platesof the carriage. This leavesthe edges of the bale free for the sewing ofthe cover, after which the pressure is relieved by releasing thepawl-links of the jacks from the ratchet-bar, as may be doneconveniently by means of hand-levers Z, that are pivoted to eachjack-housing at its upper end, Fig. 6. The bale may then be pushed outof the carriage and thelatter moved back into the lower box ready forthe operation to be repeated.

The raising and lowering of the top box A can be accomplished by mainstrength; but as a further improvement I have shown mechanism for aidingin the operation, consisting of a toothed rack-bar 20, which is pivotedto the upper box at 21 and intermeshes with a pinion 22 on the lowerbox. The shaft of this pinion is provided with a crank 23 and serves topivotally support a triangular plate .24, in the corners of whichantifriction pins are mounted in position to engage and guide the backof the rack-bar and hold it in fixed relation to the pinion. Now byturning the crank 23 the rack-bar 20 can be positively projected andmade to swing the box A up about its hinges to a point where the centerof gravity of the box falls inside of the hinge, after which the crankmovement may be reversed to ease the box down until it comes properly torest upon the lower box A. Conversely when the upper box is emptied ofits contents it may be swung back upon the ground again by turning thecrank so as to tip it back off the lower box and then reversing themotion to lower it upon the ground. In either case the box may beassisted over the dead-center point by hand, if necessary, butordinarily its momentum will suffice for the purpose.

As herein shown the handles H of the jacklevers 14 are made removableand are designed to be thrust through holes 26 in the upper edge of thetop box A when open, Fig. 4, so as to prevent the material within thebox from starting to fall out before it is completely swung over uponthe lower box B, these handles being later withdrawn and used to operatethe jacks. An antifriction-roller 27 is also herein shown as journaledin the upper end of each jack-housing to engage the back latchbar 11 andresist the outward pressure of the latter due to the pull of the barsupon it, as shown in Fig. 6. This figure also shows the improved form ofspring S provided for normally maintaining the links in engagement withthe latch-bars, the same being made of heavy spring-wire bent tosuitable form and clamped to the jack-housing by a nut 28 or the like.

The edges of the bag or cloth E require to be firmly held in order toprevent their being drawn down into the lower box B during thecompressing operation, and to this end two of the opposite sides of thebox are provided with rocking rods 29, which are held by cleats 30,

IIO

so that they can be oscillated through a considerable angle by theirends 31, the latter being bent outwardly to form handles for turning therods, as shown in Fig. 8. These rods are provided with a number of sharppoints 32, onto which the cloth can be pressed and which when the rodsare turned down will then prevent the edge of the cloth from being drawninto the box, the rods 29 being locked in position to hold the pointsdown by loops 33, which may be swung up over the handles 31.

To enable the carriage C of the press to be moved easily into and out ofthe box B, it is herein shown as mounted upon rollers c, and as afurther improvement these rollers are herein shown as groovedorotherwise formed to run upon-tracks T, that are extended beneath thepress on any foundation.

The press thus described is obviously simple and inexpensive in itsconstruction and weighs so little as to be readily portable, while atthe same time it is very powerful and can be made more so within anyreasonable limit by varying the proportions of its jack devices. It isconvenient to handle and can be rapidly operated without undue exertion,and while more particularly designed as a woolpress is adapted to beequally well used for baling cotton, hay, or any other material whichcan be packed into it.

In Fig. 11 I have shown a somewhat modified form of press embodying manyof the same features of the construction, but in which the separatecarriage is dispensed with, the

jack being bolted directly to the sides of the press, which thus takethe place of the standards 6. This form of press is designed to bemanufactured at still lower cost than the press first described, and tothis end is constructed almost entirely of wood, its boxes being boundaround with bands formed of wooden beams joined together at their endsby diagonal bolts. The operation of this device is the same as that ofthe press first described, except that the bale is removed directly fromthe lower box when the hinged side of the latter is swung back andexcept that in consequence the bale must be sewed up within its envelopbefore being removed from the box.

The improved mechanism heretofore described for swinging the upper boxupon its hinges may be equally well applied to the modified constructionlast referred to, if so desired, and this mechanism may also be founddesirable in various connections where a simple and etfective powerdevice for raising and lowering a load under similar circumstances isrequired.

Fig. 12 shows how the press could be utilized and operated in ahorizontal or upright position independently of either of the boxes byplacing the material to be pressed between the pressureplates andoperating the levers as hereinbefore described. The material so pivotedto the top box,

compressed may then be secured in that form by having bands or otherwires around the bale and fastening the ends.
